Electrocoagulation of leachate samples was performed by using aluminium and iron electrodes. The objective of study was to optimize the parameters such as current density, electrolysis time and pH for maximum removal of chemical oxygen demand by electrocoagulation process from landfill leachate collected from Deonar landfill in Mumbai, India. Landfill leachate was found to have Turbidity (177 NTU), Chemical oxygen demand (2300 mg/l), low BOD/COD ratio (0.10) and Total solids (10910) mg/l respectively. The Chemical Oxygen Demand (COD) of leachate sample was found to be 2300 mg/l and Biochemical Oxygen Demand (BOD) confirming that it was old or stabilized leachate. 47% COD was removed at current density of 466A/m2 with optimum electrolysis time of 60 mins and pH 8 with aluminium electrode while for iron electrodes, the COD removal efficiency came out to be 56% at current density of 466A/m2, optimum electrolysis time 90 mins and pH 6.
